I am not in this earth by chance. I am here for a purpose and that purpose is to grow into a mountain, not to shrink to a grain of sand. Henceforth will I apply all my efforts to become the highest mountain of all and I will strain my potential until it cries for mercy.

The moving power of mathematical invention is not reasoning but imagination.

comment Need some facts about Newton-Schulz iterative method and its application to sparse matrices
Dear sir, thank you very much for the answer. But, I want to know I want to know whether Newton's method work well for sparse matrices? Also, whether for the sparse matrix $A$, its inverse $V_k$ by Newton's method preserves sparsity?
